Player during game must build structures in space, collect minerals and energy to protect his buildings from enemy ships. Here are some tips how to play: 1) First build Solar station, and energy relays. Without them other buildings will not work (no power) 2) After that build extractors for collecting minerals from asteroids. 3) For defence purposes build cannons - you have three kinds: laser, rocket and atomic. All have different range and force. 4) If your structures are damaged you can use repair station for repairs. Ships are sent in waves, and there are few kinds of ships - faster or slower and with little fire power and big fire power. Every next wave is stronger, so dont wait, and be carefull.
